Image bit depth (Variable Control Field - Physical Description Fixed Field) |
Character position definition and scope:
A three-character number specifying the exact bit depth of the scanned image(s) that comprise(s) the electronic resource, or a three-character alphabetic code which indicates that the exact bit depth cannot be recorded. Bit depth is determined by the number of bits used to define each pixel representing the image. Since only exact bit depth is useful, coding should not include missing digits represented by hyphens ( - ). Three fill characters ( ||| ) are used when no attempt has been made to code this data element.
Record requirements for National-level and Minimal-level records: Optional.
